Spatial In-Memory Big data Analytics

Simba is a distributed in-memory spatial analytics engine based on Apache Spark.
It extends the Spark SQL engine across the system stack to support rich spatial queries and analytics through both SQL and
DataFrame query interfaces. Besides, Simba introduces native indexing support over RDDs in order to develop efficient spatial operators.
It also extends Spark SQL's query optimizer with spatial-aware and cost-based optimizations to make the best use of
existing indexes and statistics.
